Title: Tape format to facilitate error concealment and apparatus for recording and/or replaying same
IPC: G11B5/008
Filed: 1981-04-03
Abstract: Sequentially occurring packets of information (1, 2, 3...) are seperated in a tape format by the statistically significant dropout length (SSDL) of the tape to enhance the reliability of conventional dropout error concealment techniques. Due to the statistically significant dropout length separation between the packets of information, each packet of erroneous (B) information (e.g., 2, 6, 10) is replayed in sequence to adjacent packets of statistically reliable (G) information from which estimated packets of information can be derived to conceal the packets of erroneous information. <IMAGE>

Title: Transmission systems for transmitting signals over power distribution networks, and transmitters for use therein
IPC: H04B1/69
Filed: 1982-02-18
Abstract: A transmission system for transmitting digital signals over an electrical power distribution network, eg for load management and/or remote meter reading purposes, comprises means for generating spread spectrum signals (as described chirp signals) whose lower frequency lies above 15 kHz. Modulating means is provided to modulate one or more chirp signals onto the network voltage to represent each occurrence of a particular bit value (ie a 0 or a 1) of the digital signal to be transmitted. The frequency range of the chirp signals preferably covers 64kHz to 150 kHz. If desired, a different kind of spread spectrum signal, for example a pseudo-random signal, can be used in place of a chirp signal. With the use of spread spectrum signals it is more probable that at least part of the frequency range will be received and hence that data will be received correctly despite changing nulls in the power network. <IMAGE>

Title: Reactor for heterogeneous catalytic synthesis and method for its operation
Inventor: ZARDI UMBERTO
IPC: C07C29/152
Filed: 1982-06-24
Abstract: A reactor for the catalytic production of e.g. ammonia, methanol and similar substances has at least one catalyst basket (C1, C2) composed of an outer perforated wall (T1, T3), an inner perforated wall (T2, T4) and a base (S1, S2); the whole of the axial length of the outer wall is perforated, the inner wall is perforated over a smaller axial length than the outer wall, and within the inner wall is located a heat exchanger (SC1, SC2).

Patent GB-2126950-A (GB)
Title: Coloured dry transfers
Inventor: MICKIE PETER
IPC: B41M5/03
Filed: 1982-09-13
Abstract: Coloured dry transfers are produced by applying colouring from a colouring sheet to a dry transfer sheet bearing transparent or almost transparent indicia covered by a layer of adhesive. The colouring sheet has at least two layers thereon which are transferred to the adhesive on the indicia, the then outermost layer over the indicium being an adhesive layer which can act to adhere the indicium itself, its original adhesive layer and the other layer of the two (which is preferably not adhesive and which was outermost on the colouring sheet) to a desired receptor surface when the coloured dry transfer is used. The application of colour to the transfer sheet is preferably effected by bringing the colouring sheet into contact with the transfer sheet and pressing in the area of the desired indicium with a furnishing tool.

Title: Synthetic fibre rope: monitoring strain using optical fires
Inventor: RATCLIFFE DR A T
IPC: D07B1/14
Filed: 1982-11-22
Abstract: The proposed method depends on the inclusion of a number of monitoring optical plastic fibres during manufacture of the rope such that they form an integral and continuous part of its construction. Their properties are such that when subjected to the high local strains associated with internal and otherwise undetectable damage to the rope, their optical conductivity is destroyed or reduced, and this provides a warning of impairment.

Title: Method and apparatus for the thermal treatment of heavy fuel oil
Inventor: SPENCER PETER
IPC: C10G7/06
Filed: 1982-12-09
Abstract: A method and apparatus for the thermal treatment of heavy fuel oil. Hot vacuum residue (19) from a vacuum distillation unit (18) is fed directly to burners (36) to raise stream to generate electricity in a generator (39). A gas oil stream (20) is withdrawn from the distillation unit and subjected to mild thermal cracking conditions in a heater (24) which cracks a portion of the waxes which tend to concentrate in the heavier gas oil fractions. The heated stream is mixed with the feedstock inlet stream (16) and so serves to provide the heat energy necessary to operate the distillation unit.

Title: Signal processing circuit in a seeker for target seeking missiles
Inventor: HOCH HEINZ
IPC: G01S3/789
Filed: 1983-05-19
Abstract: Control of an adaptive limiter 74 within a target seeker is modified so as to reduce the risk of the seeker being deceived by a decoy ejected from the target. The seeker is of the kind in which a target within an inner zone of small target deviations generates (at the limiter input) a frequency-modulated signal whilst a target within an outer zone surrounding the inner zone generates an amplitude-modulated signal. The generated-signal amplitude normally controls (40,44,68,72) the threshold of the limiter 74, but this control loop is temporarily broken (64) when a decoy causes a large-amplitude a.m. signal to be superimposed on the f.m. signal.
